Located above each of the poles we find a semi-permanent low pressure. This low pressure is almost always present, and is the cause for many of the storms that follow the westerlies into the continents of the Earth.

While much more prominent in the winter, these subpolar lows generally exist above 60 ° of latitude either north or south.

Polar Easterlies

The subpolar lows generally cause the winds above 60 ° latitude to move from the east towards the west. We call these winds the polar easterlies.
